ICE-MAKING APPARATUS.

Specification of Letters Patent. Patented Dec, 31, 1912.

Application filed August 15, 1911. Serial No. 644,131,

To all whom it may concern:

Be it known that I,.SAMUEL R. BELL, a citizen ofthe United States, and a residentof Beaumont, in the county of Jeflerson and State of Texas, have invented a new and Improved Ice-Making Apparatus, of which the following is a full, clear, and exact description.

. My invention relates to ice making apparatus, and it has for its object to provide one having combined means for making the ice and for cooling the brine which is used. in the ice making process, thereby dispensing with additional apparatus for cooling thebrine. v

Additional objects of the invention will appear in the following complete specification, in which the preferred form of the invention is disclosed.

In the drawings similar characters of ref erence indicate correspondingparts in both the views in which- F i gurc 1 is a perspective view partially in section showing my improved ice making apparatus; and Fig. 2 is a transverse sectional elevation of Fig. 1.

By referring to the drawings it will be seen that a large insulated tank 5 is provided, in which is disposed a plurality of expansion tanks 6, these expansion tanks 6 having outer walls 7, and inner walls 8, which are spaced from each other, and which are held relatively to each other by pins 9. These expansion tanks 6 rest on blocks 10, disposed at the bottom of the tank \Vithin the inner walls 8 of the expansion tanks 6, there are blocks 11, on which are supported water tanks 12, these water tanks 12 being spaced from the inner walls 8. of the expansion tanks. A pipe 13 leads through an opening 1%, in the end of the tank 5, this pipe 13 having branches 15, which connect with the interior of the expansion tanks 6, near their top. The branches 15 are commanded by valves 16. A pipe 17 also extends through an opening 18 in the end of the tank 5, this pipe 17 being connected with depending branches 19, the said branches it) being commanded by valves 20, and connecting with the interior of the expansion tanks (3 near their bottom. Liquefied amoi'nnia is supplied to the expansion tanks 6, by the pipe 17 andthe branches 1?, the ammonia, after it'has been expanded, being carried away by the branches 15 in the pipes 13, so that it may be again liquefied in a manner well understood in the art. A pipe 21 is disposed in the tank 5, and near its inner side, branches 22 being connected with this pipe, which ex-* tend through the outer and inner walls 7 and 8 of the expansion tank 6, to the space between the inner wall 8 of the,expansion tank and the Wall of the Water tank 12, these branches 22 being commanded by valves 23. There is also a pipe 24, which extends around the tank 5 depending branches 25 being connected with this pipe 2st, these branches 25 extending through the outer and inner walls 7 and S of the expansion tank 8, to communicate with the space between the inner wall 8 of the expansion tank and the wall of the water tank 12, near the bottom of the said water tanks. These depending branches 25 are commanded by valves 26. There-are two pumps 27 having pipes 28 leading therefrom, these pipes 28 being in communication with the pipe 21. There are also pipes 29, which connect the pumps 27 with the pipe 2st. Leading from the pipes 29 there are depending branches 30, commanded by valves 31,.

these branches 30 communicating with the lnterlor of the tank 5, near its bottom. The branches 32 whlch are in commuincatlon with the pipes 28 communicate with the interior of the tank 0, near its top. The branches 32 are commanded by -.alves 33.

The branches 30 serve to afford. communication between the brine pumps 27 through the pipe 29 and the bottom of the large insulated tank 5, andthe branches 32 serve to afford eomn'iunication between the brine pumps and the top of the insulated tank 5, through the pipe 28.

It will be understood that the liquid ammonia is conveyed to the expansion tanks 6 between their outer and inner walls, where the ammonia expands, cooling the brine in the large outer tank 5, and also the brine which is disposed between the inner'walls 8 of the expansion tanks and the water tanks 12. The ammonia is then carried away back to the compressor, where it is aga-inlique- .fied, to be again conveyed to the expsnsion tanks. The brine within the tank 0, and

also the brine disposed between the inner Walls of the 'expansioa tank sand.the wa s of the water tanks 12 is cooled by the vaporization of the ammonia, and after the plant has been in operation a short time it will be found that the brine when it enters the space between theinner walls 8 of the expansion tanks, and the walls of the water tanks 12,

will be at such a low temperature that it will be unnecessary for the ammonia to reduce the temperature of the-brine more than a few degrees, before the brine will be coldenough to freeze the water in the water tanks. In my apparatus the ice ismanufactured rand the brine is cooled all in the same tank, which :does, away with a separate cooling between the inner walls 8 of the expansion tank, and the walls of the tank 12.

The brine in the large insulated tank 5 v and outside of the expansion tank 6 may be used for refrigerating purposes, and after it has become cold it acts as an insulation for the expansion tanks 6. This brine in the large insulated tank 5, and outside of the expansion tanks has a tendency to support the freezing powers of the ammonia in the expansion tanks. The brine flowing through the pipe out of the large insulated tank 5 mixes with the warm brine flowing from between the expansion tank 6 and the tank 5, and prevents the working of the plant from becoming impaired by the heated brine.

Two brine pumps are provided for more complete circulation of the brine both between the inner wall 8 of the expansion tank and the water'tanks 12, and in the large outer tank 5. It will be understood that should one brine pump be damaged the apparatus may be used while repairs are being made.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:

the expansion tank,--a third tank in which the expansion tank is disposed, and a conduit connecting the third -tank with the opening between the water tank and the inner. wall of the expansion tank.

3. In an ice making apparatus an expansion tank having side walls, spaced one with the other, a water tank disposed within and spaced from the inner wall of the expansion tank, a third tank in which the expansion tank is disposed, a pipe having two branches one opening into the space between the water tank and the inner wall of the expansion tank, and the other leading into the third tank, and a pump for forcing a fluid through the pipe.

4. In, an ice making apparatus an expansion tank having side walls spaced apart, one within the other, a water tank disposed within and spaced from the inner wall of the expansion tank, a third tank in which the expansion tank is disposed, and a conduit connecting the third tank with the opening between the water tank and the inner wall of the expansion tank, and a pump for forcing a fluid through the conduit."

5. In an ice makin apparatus an expan sion tank having si e walls spaced apart one within the other, a water tank disposed within and spaced from the-inner wall of the expansion tank, a third tank in which the expansion tank is disposed, two pipes each having two branches one of the pipes on each of the branches communicating with the space between the water tank and the a relatively large supply of brine, and means for the circulation of the brine from the insulated tank to the space between the inner wall of the expansion tank and the wall of the water tank and back to the insulated tank so that the temperature of the brine need be lowered only a fewdegrees in the space between the inner wall of the expansion tank and the wall of the water tank.

7. In an ice making apparatus an expansion tank having side wallsspaced apart one within the other, a water tank disposed within and spaced from the inner walls of the expansion tank so that the said space will accommodate a'limited supply of brine,

an insulatedtank in which the expansion tank is disposed for the accommodatmn of a relatively large-supply offbrine, -a brine pipe having branches communicating with the top of the insulated tank and with the top of the space between the inner ivall'cf the expansion tank and the wall of the water tank, a second pipe with branches communicating with thebotton'n of the insulated tank and with the bottom of the space between the inner Wall of the expansion tank and the Water tank, and a pump 10 connected With the brine pipes.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
